Answer 2

Answer:

The shopkeeper should sell 10 toffees for a rupee.

Step-by-step explanation:

A shopkeeper bought 12 toffees for one rupee.

$\text{The cost price of 12 toffee}=1$

$\text{The cost price of one toffee}=\frac{1}{12}$

In order to gain 20% profit.

$\text{The selling price of one toffee}=\frac{1}{12}+\frac{20}{100}\times \frac{1}{12}$

$\text{The selling price of one toffee}=\frac{1}{12}+ \frac{1}{60}$

$\text{The selling price of one toffee}=\frac{5+1}{60}=\frac{1}{10}$

$\text{The selling price of one toffee}=\frac{1}{10}$

$\text{The selling price of 10 toffee}=1$

Therefore, the shopkeeper should sell 10 toffees for a rupee.
